Immediately cut power by pulling a cable. These switches are often used to turn off production lines and material handling systems in an emergency. All have positive-force, snap-open contacts that open a circuit when actuated, even if a spring fails or the contacts stick. The contacts will remain open until you tension the cable and reset the switch.
Two-direction switches can be used with tension springs (not included) to open contacts and stop machinery if the cable breaks.
Switches with a power indicator illuminate when the cable has been pulled.
Switches with a tension indicator let you visually confirm that tension is set correctly in the system.
Switches with an emergency stop button can be shut off either by their button or cable. They’re often installed where equipment may block access to the cable.
Accessory kits (sold separately) simplify the installation of a new switch.

Cable-Pull Emergency Stop Switches with Restart Switch

Tug on the cable anywhere along your line to immediately cut the flow of power. This multi-functional unit also sends a signal to restart machinery with the push of a button, doing the job of two units in one. When you’re ready for production to continue, tighten the cables until signaled by the tension indicator and then press the restart button. When the power is off, a light goes on, so you can check the status of your line from far away. They have an emergency stop button, too, so you can halt machinery even if access to the cable is blocked.
Two-direction switches have cables connected to both sides, so they can be installed midway through your system instead of at the end of the line. Use them with long runs of conveyor.
